Here are several common configuration errors that can be easily solved.

On This page:

Login page display "Unable to renew license"

You see the following error message on frevvo's login page when you try to access the login page in your browser at http://<yourhost><port>/frevvo/web/login

   "Unable to renew license for 1 attempt(s). Your license will expire in 2 day(s). Please contact frevvo for help."

You will also see the following error in the tomcat log file:

   WARNING: License monitor: failed to authorize start up for 0 attempts. Next attempt in 1 hours.

This is often caused by running your web app container (ex: tomcat) under a SUN JDK or JRE that is not version 1.5.0 update 8 or later. Verify that you are running with the required JDK or JRE. If not, to solve this, download & install JDK or JRE 1.5.0 version 8 or later from http://www.sun.com. Set your JAVA_HOME on windows to the JDK or JRE install directory on your computer. Then restart your web app container.

This may also be caused by an incorrect string content in your customer.lic file. Look in the location where you put your frevvo users directory. Verify that a a customer.lic file exists in a subdirectory named .frevvo. Edit the customer.lic file and verify that the content is correct. This file must contain a single line which is the license key sent to you via email when you downloaded frevvo.zip.

Unable to contact license server

This may be due to your external http traffic being routed through a proxy server.

If your company uses a [http://en.wikipedia.org/wiki/Proxy_server Proxy Server] your frevvo Form Server may not be able to communicate with the license server directly. frevvo has web configuration parameters to enable communication from the Form Server to the license server via your proxy. Edit the following parameters in <frevvo installdir>/frevvo/tomcat/webapps/frevvo/WEB-INF/web.xml or override them at the container level by putting the parameters into frevvo.xml, eg: on Tomcat in tomcat/config/catalina/localhost/frevvo.xml.

ParameterDescription
frevvo.proxy.hostHTTP Proxy Host
frevvo.proxy.portHTTP Proxy port
frevvo.proxy.usernameHTTP username
frevvo.proxy.password HTTP password
 frevvo.proxy.ldap true | false

 Set frevvo.proxy.ldap to true to enable NTLM authentication proxy access.

The trial license fails to install

Sometimes, especially on Windows, the license is not accepted. If so, please restart your frevvo server and try again. Please, check the frevvo forum or contact us for additional help.

More License Issues

License issues have several common causes. A proxy server can be the cause of these error messages.

  • Unable to contact license server
  • Unable to renew license. Your license will expire in <n> day(s)

To diagnose license issue:

  1. View the frevvo [[V4_Admin_Home_Page#Version_Information server configuration]] page and verify that you have a valid unexpired license key.
  2. Open a browser on your frevvo server machine and try to reach the url: https://www.frevvo.com/security/securehttp. This server should return the message "You have reached the frevvo licensing server. Thanks for you interest in frevvo Live Forms.".
  3. Second open the log files in <frevvo installdir>/frevvo/tomcat/logs and scan for license related error messages.
  4. Read solutions for [[#Proxy_Server_configuration | proxy server configurations]] if the log file indicates that your frevvo server is unable to contact the license server.
  5. Read solutions for the issue [[Installation_Help#Login_page_display_.22Unable_to_renew_license.22 | unable to renew license]]

If you need further help send the results of all above diagnostic steps to support at frevvo.com.

frevvo fails to install/start as windows service

Running c:\frevvo\Install Service, fails to install the frevvo service and the frevvo fails to run as a windows service. This problem is solved by adding %JAVA_HOME%/bin to the system PATH Environment Variable.

If this fails to solve the problem even with setting of JAVA_HOME the tomcat service may not be able to find msvcr71.dll even though it is in the bin directory of your JDK or JRE installation, copy msvcr71.dll from the bin directory of your java installation the bin directory of your tomcat installation or to your C:\WINDOWS\System32 directory.

You may see these errors in the windows service log file:

[174 javajni.c] [error] The specified module could not be found.
[986 prunsrv.c] [error] Failed creating java C:\Program Files\Java\jdk1.6.0_07\jre\bin\server\jvm.dll
